Movable Dam—Gate Selection Procedureby Howard A. Mayo, Jr., Williams & Broome Inc, Exton, PA, USA,
Abstract: Very few new dams are now being considered, particularly for waterpower and even more specifically for low head waterpower in the lower reaches of major rivers. The City of Harrisburg, Pennsylvania, on the other hand, is not only considering such a project, but has obtained a FERC permit and funding. This paper describes the project background and gate selection procedure. It includes descriptions of the several gate types considered, the evaluation process, evaluation factors, and general conclusions as they apply to the specific project. The general cost analysis and conclusions provide a basis for the more general application of this project concept - a concept which enhances the feasibility of new low head waterpower projects that will not encroach beyond existing flood plains.
